Operation Definition
Cutting out or off, without replacement, a portion of a body part
Procedure Overview
Tendon excision procedures cut out and remove a portion of a tendon without replacing it, typically to address a tumor, a chronically degenerated segment, a painful nodule, or scar tissue that is limiting motion. A well-known example is excision of a trigger finger nodule or a portion of tendon affected by tenosynovitis that has not responded to more conservative treatment, as well as biopsy of a suspicious mass for diagnostic purposes.
Because only part of the tendon is taken and the remainder is left in place, the surgeon must weigh how much tissue can be safely removed without compromising the tendon's mechanical function. In many cases the excised tissue is sent to pathology, which both confirms the diagnosis and distinguishes this procedure from techniques that simply destroy tissue in place.
Anatomy & Axis Detail
Ankle Tendon, Left
The left ankle tendon group, comprising the Achilles, tibialis posterior, tibialis anterior, and peroneal tendons, governs the mechanics of push-off, foot inversion and eversion, and hindfoot alignment. Excision of diseased tissue is performed for conditions such as insertional Achilles tendinopathy, peroneal tendon tears with degenerated segments, or posterior tibial tendon dysfunction associated with progressive flatfoot. Surgeons typically resect only the pathologic portion to preserve the tendon's structural continuity and function. The tendons' passage through narrow retinacular tunnels behind the malleoli means the surgical field is compact, and adjacent structures like the sural and tibial nerves must be protected during dissection. Precise identification of the specific tendon excised is essential given the overlapping anatomy at the ankle.
Approach: Percutaneous
Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.
Qualifier: Diagnostic
Applied chiefly to Excision, this qualifier marks that tissue was removed specifically for diagnostic purposes, i.e., a biopsy intended for pathologic evaluation rather than to treat disease. It distinguishes biopsy-type excisions from therapeutic excisions of the same body part, which are coded without this qualifier even though the physical technique may be identical.
Coding & Documentation
A code from this family is appropriate when the operative note documents cutting out and removing a defined portion of tendon tissue, with the remaining tendon left intact and nothing reconstructed at the same time. Look for language describing a specimen sent to pathology, the anatomic tendon and location, and confirmation that the entire tendon was not removed, which would instead point toward Resection.
A common mistake is coding Excision when the whole tendon was actually removed, since ICD-10-PCS distinguishes cutting out "all or a portion" only when characterizing the two operations differently, that is, Excision for a portion and Resection for all of a body part. Coders also sometimes overlook a concurrent repair, such as a tendon graft or suture closure performed after excision, which requires a separate code if it meaningfully restores structure beyond simple wound closure.
